I get the error "403
Access to this resource on the server is denied!"
when I was trying to add a theme in WordPress for the first time after purchase.
Did you follow our official documentation during the installation process?
Can you check if the same thing happens when you try to install some free theme like Twenty Twenty-Two, please?
So does this happens when you install the Betheme or try to edit pages?
Can you explain in more detail when it happens, please?
